For each trip, a taxi company charges a fixed fee of $2.00 plus $0.75 for each \(\frac{1}{2}\) mile or fraction of \(\frac{1}{2}\) miles. If, for every number x, [x] is defined to be the least integer greater than or equal to x, then which of the following represents the company's charge, in dollars, for a trip that is r miles long?
A. 2.00 + [\(\frac{0.75r}{2}\)]
B. 2.00 + 0.75 [\(\frac{r}{2}\)]
C. 2.00 + 0.75[r]
D. 2.00 + [1.5r]
E. 2.00 + 0.75 [2r]
A. 2.00 + [\(\frac{0.75r}{2}\)]
B. 2.00 + 0.75 [\(\frac{r}{2}\)]
C. 2.00 + 0.75[r]

Fixed fee= 2.00
fee dependent on miles = 0.75 per 1/2 mile or fraction there off
no of miles = r
no of 1/2 miles= 2r..
and to convert 2r into integer mile [2r]..
total cost on miles= 0.75[2r]..
total = 2.00 + 0.75 [ 2r]
E
